Abstract:

* Recent studies suggest that rhizosphere soil microarthropods may have a major role in determining soil nitrogen availability. Desert soil microarthropods are consumers of soil bacteria, fungi, and nematodes, thus they accelerate mineralization processes by causing turnover in immobilized nitrogen. [It is] hypothesized that changing densities of soil microarthropods would result in changes in nitrogen availability. In order to test this hypothesis, Erionueron pulchellum rhizosphere soil samples were taken monthly from control plots, plots irrigated with 6mm/wk, plots soaked with chlordane (to remove microarthropods), and plots treated with chlordane that were irrigated with 6 mm/wk. These samples were analyzed for available inorganic nitrogen (NO3 and NH4), gravimetric soil moisture, plant shoot and root biomass, plant shoot and root total nitrogen, plant growth, microarthropod and nematode densities.

Data Use and Acknowledgement StatementThis dataset is released to the public and may be used for academic, educational, or commercial purposes subject to the following:ObjectivesThe Jornada Basin LTER Information Management System provides protocol and services for data collection, verification, organization, archives, and distribution.Quality Assurance StatementData managers interact with researchers during the entire scientific process--from the initial planning of sampling designs and field data collection to archiving and distribution of long-term data. The goal of data management is to build and maintain an archive of Jornada Basin LTER data files that are fully documented, error free, and organized in useful ways. Our protocol for data collection and processing seeks maximum interaction between researchers and data management personnel to avoid confusion and potential loss of data or problems with integrity of data. The data manager helps researchers to construct data forms that allow convenient data entry and analysis. Data documentation forms are completed by principal investigators prior to data entry. Data are entered into computer data files by data entry personnel using programs that error- check and verify the data as it is entered. Computer files are subjected to further verification by graphing and/or error-checking programs, and/or examination by field investigators. Error-checked data files are stored with associated documentation files on floppy disks and on a hard-disk database. Back-up data files are maintained as "hard-copy," on multiple floppy disks, and on read/write 30- year magneto-optical disks. Various sets of these data are stored at different sites on the NMSU campus. The final responsibility for quality assurance (both in data and documentation content) rests with the principal investigator who submits the data for inclusion in the Jornada Basin LTER Information Management System. To facilitate quality assurance, the data management staff will provide copies of data and documentation submitted by a principal investigator to that investigator upon request.Policy on Submission of DataAll data collected during a calendar year should be submitted to the Jornada Basin LTER data manager prior to July first of the following year. Data must be submitted with standard Jornada Basin LTER forms (both Project Abstract and Data Set documentation) which include objectives of the study, methods, as well as format and content of the data.Data Access PolicyData will be made publicly available no later than 2 years after submission of the data unless an earlier date is specified by the principal investigator. In the event that an extension of the 2 year period is necessary, the principal investigator may petition the Jornada Basin LTER Executive Committee for a longer protected period.Data Acknowledgement PolicyIndividuals and institutions utilizing data from the Jornada Basin LTER database are requested to place the following acknowledgment in any publication in which these data are mentioned: Data sets were provided by the Jornada Basin Long-Term Ecological Research (LTER) projects. Funding for these data was provided by the U.S. National Science Foundation (Grants DEB-92-40261 and DEB 94-11971). Please send 1 copy of any publication that cites Jornada Basin LTER data to: John P. Anderson Jornada Experimental Range P.O.
